This page describes Sugar's Python programming environment. The API available to non-Python activities is described on the Low-level Activity API page.

Sugar is written in Python and uses a variety of open source packages. Programming in the Sugar environment requires a basic understanding of the Sugar user interface, supporting third-party packages, and built-in Sugar packages.

Traditional software packages are built against application programming interfaces. Sugar runs Activities instead of applications, but from a developer's point of view, it's the same thing.

The platform API Reference includes a collection of pointers to documentation including automatically generated PyDoc documentation for Sugar and related libraries.

Third Party Packages

  • Abiword - Document writer
  • ATK - GNOME Accessibility Toolkit
  • Avahi - network service discovery system
  • GTK - GNOME Toolkit
  • GStreamer - multimedia framework
  • Cairo - 2-D graphics library
  • D-BUS - message bus service
  • Evince - document viewer
  • HippoCanvas - generic user interface widget - now deprecated use GTK layout managers
  • Matchbox - graphical windows manager
  • Pango - GTK package for text rendering
  • X Window System - the tried-and-true ancient X11 display libraries
  • Xul - XML User Interface Language
